Free Rice

No, guys, this is not a freebie, sorry.
When reading the Pioneer Womans blog, I stumbled about
FreeRice.com
They have little quizzes to test your vocabulary, grammar, foreign language skills, maths, chemistry or geography- every correct answer you give generates a donation of 10 grains of rice to a poor region (apparently financed by a little banner on the bottom of the page)
Train your brain, donate a grain...
it couldn't be easier. I spent about 45 minutes on the page before writing this post and it honestly is a great way to get your brain into gear!
By the way, I cheated at some point and did the german language quiz, but it generated loads of grains, so-
no harm done :)
Go on, folks, you know you want to.
